ICMJE vs COPE: Criteria vs Dispute Guidance
ICMJE sets the 4-criteria authorship test; COPE gives editors process guidance for disputes, ghost, and guest authorship. How the two differ and interact.
Side-by-side comparison
| Dimension | ICMJE | COPE |
|---|---|---|
| Full name | International Committee of Medical Journal Editors | Committee on Publication Ethics |
| What it primarily is | A small working group of medical journal editors publishing a single evolving recommendations document | A large international membership organization for journal editors and publishers |
| Core authorship output | The 4-criteria authorship test ("Defining the Role of Authors and Contributors") | Flowcharts and discussion documents for handling authorship problems (e.g. ghost/guest/gift authorship) |
| Sets who qualifies as an author? | Yes — this is its central authorship function | No — its guidance refers back to published criteria such as ICMJE’s |
| Adjudicates a specific authorship dispute? | No — explicitly directs unresolved disputes to the researchers’ institution | Provides a structured investigative process for editors, not a binding ruling |
| Primary audience | Authors and journals, as a submission standard | Editors, as an operational playbook |
| How journals typically use it | Cited in instructions-for-authors as the authorship bar submissions must clear | Adopted via membership as the journal’s internal process for investigating reported problems |
Common questions
FAQ
Does ICMJE resolve authorship disputes between co-authors?+
No. ICMJE’s own Recommendations state that if authors cannot agree on who qualifies for authorship, the institution where the work was performed — not the journal editor — should be asked to investigate. ICMJE sets the qualification criteria; it explicitly does not adjudicate individual conflicts.
Is COPE a substitute for ICMJE’s authorship criteria?+
No. COPE does not publish its own competing authorship criteria. Its flowcharts and guidance documents point editors back to published criteria such as ICMJE’s four-part test as the standard to apply, while COPE itself supplies the process for investigating a specific case.
Do journals have to choose between following ICMJE or being a COPE member?+
No, and most journals that cite both do not treat them as alternatives. A journal can require ICMJE-style authorship criteria from its authors while also being a COPE member and using COPE’s Core Practices and flowcharts as its internal process for handling reported problems. The two are commonly used together.
What should a researcher do if they believe they were unfairly left off a paper’s author list?+
Raise it directly with the corresponding author and co-authors first, referencing the applicable authorship criteria (usually ICMJE’s). If that does not resolve it, or the manuscript is already under review or published, the journal’s editor can apply COPE-style process (for a manuscript still in review) or the matter can be escalated to the relevant institution’s research integrity office, which is where ICMJE directs unresolved disputes.
Does COPE have any enforcement authority over member journals?+
COPE is a membership and guidance organization, not a regulator. It sets Core Practices that member journals and publishers agree to follow and can investigate complaints about member conduct, but it does not have legal or regulatory authority over research institutions, and it does not overturn a journal’s own authorship or retraction decisions — it advises.
